The AUG A3AW (Alpine Warfare)

Originally designed for the austere conditions of the Alps, the STG77 has served with the Austrian military since its adoption in 1977. The STG77’s original 1.5x integral optic was groundbreaking as most military rifles of the time were issued with iron-sights. While technology has advanced, the Austrian armed forces have stuck with an integral optic for its durability and ease of maintenance.

For the first time in years, Steyr Arms USA is offering a very limited run of STG receivers (no short side rail). These receivers have been coupled with the newly developed and issued AUG 3x 60mm SF Mildot optic. The SF 3x is the latest in the longline of AUG integral optics. Designed for extended combat in the Alpine environments of central Europe, the SF 3x is constructed for 70 series aluminum and sports a simple but precise adjustment system for absolute reliability in adverse conditions. With two additional QD sling points, detachable picatinny rails, optional riser, and additional side rail, the SF 3x has been optimized for this limited-run STG receiver.
